Arctic explorer Roald Amundsen's former ship raised to surface

After six years of hard work, a team of Norwegians has succeeded in pulling the Maud - a ship that once belonged to famed Arctic explorer Roald Amundsen - from its icy grave in Nunavut waters near Cambridge Bay in Canada. The ship has been lifted to the surface and is now being preparing for winter before it can be brought back home to Norway

Antarctic mystery solved? Scientists say ocean fossils found in mountains are cause for concern over future sea levels

Tiny ocean fossils distributed widely across rock surfaces in the Transantarctic Mountains point to the potential for a substantial rise in global sea levels under conditions of continued global warming, according to a new study.

Scientists pinpoint beginning of current global warming trend

Human-induced global warming began much earlier than previously thought. New research suggests that warming started about 180 years ago near the beginning of the Industrial Revolution. Researchers in Australia found evidence for the early onset of warming after analysing 500 years of climate data from ice cores, corals, sediment layers and tree rings.

Seals help solve Antarctic bottom water mystery

Oceanographic instruments attached to the heads of Antarctic elephant seals have assisted scientists better understand the role melting ice shelves are having in regulating global ocean temperatures. During their foraging dives the animals collected data and helped researchers to identify a new source of bottom water production in East Antarctica.

Small fish in the bigger picture of the Southern Ocean ecosystem

The Southern Ocean is still a very big white spot on the knowledge map despite its importance for the world’s climate and as an important habitat for many marine organisms. Now, scientists from Australia and the European Union have joined forces to better understand the role of micronekton in the marine food web, holding the first project meeting of the new partnership in Hobart today. The Mesopelagic Southern Ocean Prey and Predators (MESOPP) project focuses on micronekton, which are small fishes, crustacean, squids and jellies that measure between 1 and 20cm.

Auroras move to the rhythm of Earth’s magnetic field

The majestic auroras have captivated humans for thousands of years, but their nature – the fact that the lights are electromagnetic and respond to solar activity – was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm.

Arctic Sea ice on the retreat

The Arctic sea ice diminishes every year more and more. In 2012, it had reached a sad negative record with its extension of 3.4 million square kilometers. This year, the extension reached its second lowest value with 4.1 million square kilometers which is even less than the previous record in 2007. And according to experts from the Alfred-Wegener-Institute, who had been responsible for the measurements, the trend will continue.

Radical action for more gender equality in Antarctic science

Antarctica is not a man’s world - not anymore. Women have played an important role in the advancement of Antarctic science especially in the last 50 years. An on-line collection of biographies of successful female scientists who worked in Antarctica celebrates that. Hopes are that the carriers of these women will inspire young girls to follow in their footsteps.

Grey whales in Russian Far East slowly recovering

The critically endangered western gray whale population that feeds in Russia's Far East waters is slowly showing signs of recovery, but their numbers and range are still at risk from industry activity in the region, according to a new report. Over the last 12 years, Sakhalin Energy has made important efforts to limit the impact of its operations on whales and the fragile environment. During this period, the western gray whale population has grown 3-4% annually, from an estimated 115 animals in 2004 to 174 in 2015.

Franklins long lost HMS Terror found in the Northwest Passage

When Sir John Franklin and his 128 men vanished without a trace in the Canadian Arctic in 1845, it led to the biggest and longest search and rescue missions in the history of polar exploration. More than 50 years, numerous ships and explorers made their way into the high north to look for the expedition and simultaneously for a passage through the Canadian Archipelago. The passage eventually was found, but the expedition and its two ships remained lost for almost two centuries. Until 2014, when the HMS Erebus, Franklin’s flag ship was found. Now, another search party also found the second ship, HMS Terror… almost 100 km south of its presumed sinking spot and perfectly intact.
